We apply state-of-the-art technology and processes to supply the highest quality of equipment installation & commissioning services, dynamic balancing, laser shaft alignment, preventive maintenance, and predictive maintenance. When things do go wrong, you can also count on us for your corrective maintenance.

Cornerstone has established itself as a highly respected partner with many industrial plants and process facilities in Northeast Texas, including Dallas and Fort Worth. We take pride in working closely with our clients to lower production costs and resolve reliability issues within their production constraints.

In Loving Memory

Terry Wilson

On May 3, 2019 our company Founder and Co-owner, Terry Wilson, lost His battle with leukemia and went to be with Jesus. 

When Terry & Wynell started this business in 1995 they had three goals: 1) to be a light for Christ; 2) to provide for their family; 3) to provide a way for their children to make a living and provide for their own families. Terry definitely saw those goals through to completion along with so much more. 

He was a very selfless person. His main priority was always to make sure everyone else around him was taken care of—a quality that’s reflected in so much of his work. There were countless times he would stay up half the night coming up with a “better way” to complete a project to improve overall project quality for the customer. He always took the time to share as much knowledge as he could with employees because he wanted to see them be successful. 

Terry’s wisdom and wealth of knowledge is greatly missed. His legacy, however, will continue to live on through the foundation he built for Cornerstone. We strive daily to continue to live up to the legacy he set before us, and it is our promise to our customers to never quit “doing our best” for you.

“And whatever you do, do it heartily, as to the Lord and not to men” Colossians 3:23
